[music] Hello, I’m Dr. Neal Schultz
[pause]
and welcome to DermTV.
A patient asked me, is it true that you can’t get a burn through window
glass, and I’m happy to tell you that the answer is yes. Window glass stops
the B rays, that’s called ultraviolet B rays, and those are the rays that
cause sunburn. Window glass doesn’t stop the UVA rays, those are the rays
that cause premature aging of the skin and also skin cancer but, certainly,
in your car or in your living room next to a sunny window, you’re not going
to get a sunburn. Just keep in mind that if you’re taking a medication,
that says don’t take in sunlight, because that medication is apt to cause
an allergic reaction from the sun, then that allergic reaction can occur
through sunglass, but you won’t get a regular sunburn through your window
glass.
